(Ralph Waldo Emerson (1803-1882), U.S. essayist, poet, philosopher. "Address Delivered in Concord on the Anniversary of the Emancipation of the Negroes in the British West Indies, August 1, 1844," Miscellanies (1883, repr. 1903).)
If a white person visits Africa, the black children run after him or her; trying to touch him or her. On the other hand, if a black person travels back to this white person's country, no white children come out running after him or her. Why is it so? This is something that we have to chew on and learn from; for the wisdom od nature.
